Do not track crawler, bots etc

Hello.
I use the next track code:

< script type=“text/javascript”>
var _paq = _paq || ;
_paq.push([‘trackPageView’]);
_paq.push([‘enableLinkTracking’]);
_paq.push([‘appendToTrackingUrl’, ‘bots=1’]);
(function() {
var u=“https://mypiwikdomen.fr/”;
_paq.push([‘setTrackerUrl’, u+‘piwik.php’]);
_paq.push([‘setSiteId’, 3]);
var d=document, g=d.createElement(‘script’), s=d.getElementsByTagName(‘script’)[0];
g.type=‘text/javascript’; g.async=true; g.defer=true; g.src=u+‘piwik.js’; >s.parentNode.insertBefore(g,s);
})();

< noscript >< p>< img src=“https://mypiwikdomen.fr/piwik.php?idsite=3&rec=1&bots=1” > > style=“border:0;” alt=“” />

But this don’t track bots, crawlers, and if I make request from curl I didn’t view it in piwik.
How I can track it?
P.S. My piwik version is 2.15.0

In piwik doc http://piwik.org/faq/new-to-piwik/faq_63/ describe that if I use bots=1 I can view bots, but it doesn’t work for me. I doesn’t see any bot.

Bots can only be tracked using log analytics. Using the Javascript tracking pixel excludes most bots and crawlers, as nearly all of them do not load or interpret the script content on the page.
